201017496 _ k 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種觸控面板及透明壓電片。 【先前技術】 近年來，於液晶顯示器等之顯示裝置之前面設置有作為 輸入裝置之觸控面板的顯示裝置及輸入裝置得到實用化， 正用於行動電話機等行動裝置及家電產品之操作面板等。 _ 使用有觸控面板之顯示裝置及輸入裝置可使用戶藉由按壓 畫面上之顯示而直觀地操作裝置。 於迄今為止已實用化之觸控面板中，僅可檢測用戶按壓 之位置（本說明書中，有時稱為觸控位置），而無法檢測用 戶所按壓之強度（即，按壓之高度（強度）。於本說明書中， 有時稱為觸控壓力）。另一方面，於使用有觸控面板之顯 不裝置及輸入裝置中，觸控面板係設置於顯示裝置之前 面，故而為提高顯示裝置之顯示之視認性，要求觸控面板 p 之透明性較高。 作為可檢測按壓之強度且具有透明性之輸入裝置或者與 其相似者，例如，於專利文獻丨中揭示有一種觸控面板 部，其包含用作電子紙之構件之壓電體、設置於上述壓電 體之其一之側之第1電極、以及設置於上述壓電體之另一 之侧之第2電極。 又’於專利文獻2中揭示有一種觸控螢幕系統，其包 含：第1感測系統’其係與觸控螢幕結合，確定相對於上 述觸控螢幕之各接觸的位置座標之組；以及第2感測系 143712.doc 201017496 統，其係與上述觸控螢幕結合，利用第1類型之物體確認 上述觸控螢幕之各接觸，利用第2類型之物體使上述觸控 螢幕之各接觸無效，並不具有確定上述位置座標之組之能 力；且作為第1感測系統，具體而言，揭示有一種配置於 LCD(liquid Crystal Display，液晶顯示器）之視覺區域之外 側的力感測器。 又’於專利文獻3中揭示有一種透明壓電感測器，其特 徵在於，於對向之一對透明基板之間，形成有具有壓電性 之透明感壓層、以及經由該透明感壓層而對向配置之一對 透明導電膜層。 [先前技術文獻] [專利文獻] [專利文獻1]日本專利特開2006· 163619號公報 [專利文獻2]曰本專利特開2〇〇4_534974號公報 [專利文獻3]曰本專利特開2004425571號公報 【發明内容】 [發明所欲解決之問題] 專利文獻1所揭示之觸控面板部雖然可獲得與按壓相對 應之電壓脈衝’但是觸控面板部並未將透明性作為必需之 要件，可認為其透明性衫充分。又，上料利文獻【所 揭示之觸控面板為電阻膜式，但是於⑷多點檢測較容易的 靜電電容式、（b)適於手寫輸人剌久性較高之超聲波式、 及(c)透光率較高且耐久性較高之光學式等之各具優點之 他位置檢測方式的觸把Λ 、 觸控面板中，亦需要開發出能夠檢測觸 143712.doc 201017496 控位置與觸控壓力之觸控面板。 又，上述專利文獻1所揭示之觸控面板存在難以直接轉 用現有之僅檢測用戶所按壓之位置的觸控面板之製造裝置 的問題。若於可檢測觸控位置與觸控壓力之觸控面板之製 * 造時’能夠直接利用現有之觸控位置檢測用之觸控面板的 - 製造裝置、或者可直接利用現有之觸控位置檢測用之觸控 面板自身’則將變得簡便，甚至可削減製造成本。 Φ 專利文獻2所揭示之觸控螢幕可判別假接觸，故亦可謂 其提出檢測按壓之強度的概念，但實際上具體揭示之内容 係如上所述’藉由LCD之視覺區域之外側之力感測器檢測 基板之翹曲者，其精度並不充分，且難以進行例如線性檢 測。 專利文獻3所揭示之透明壓感測器亦揭示可檢測按壓之 有無’但並未揭示能夠檢測按壓之強弱。 鑒於上述背景，本發明之目的在於提供一種觸控面板 ❹ 等，其能夠檢測觸控位置，並且能夠以高精度檢測觸控壓 力（按壓之高度（強度））。 上述觸控面板（1)透明性較高、（2)可採用各種位置檢測 方式，且（3)於其製造時，可直接利用現有之觸控位置檢測 用之觸控面板之製造裝置，或者可直接利用現有之觸控位 置檢測用之觸控面板自身。 [解決問題之技術手段] 上述課題可藉由以下所揭示之發明而解決。 第1發明之透明壓電片包含： 143712.d〇c 201017496 片狀透明壓電體層； 第1透明平板電極，其係配置於該片狀透明壓電體 一之面上；以及 ' 第2透明平板電極，其係配置於該片狀透明壓電體層之另 一之面上；且 上述第1透明平板電極包含第i透明平板電極部， 上述第2透明平板電極包含第2透明平板電極部， 上述第1透明平板電極部之輪麼於俯視觀察時包含上述第2 透明平板電極部之輪廊，或者上述第2透明平板電極部< 輪廓於俯視觀察時包含上述^透明平板電極部之輪廊。 本發明之透明壓電片可用於觸控壓力之檢測。換而言 之，本發明之透明壓電片可作為觸控壓力檢測用透明壓電 片。此處’由於來自配置於片狀透明麼電體層之面上之平 板電極之上方的觸控壓力會直接傳遞至片狀透明壓電體 層’故而能夠以高精度檢測觸控壓力。另外，上述第以 明平板電極部之輪摩於俯視觀察時包含上述第2透明平板 電極部H或者上述第2透㈣板電極部之輪廊於俯 視觀察時包含上述第1透明半把φ & 遷月千板電極部之輪廓，藉此製造 時之第1透明平板電極部盥第2读 /、第2透明平板電極部之於俯視觀 察時之偏移之容許範圍增大，狁 闽0八從而可降低製造時之不良品 率。又，藉由該構成，可檢測第1 弟透月千板電極部與第2透 明平板電極部中面積較小者輪 掏鄰之範圍内的整個區域内 之確實的觸控壓力，甚至可檢 内夕心 測所需（所設計）的寬廣區域 内之確實的觸控壓力。藉此，當 虽將本發明之透明壓電片與 143712.doc 201017496 觸控位置檢測用觸控面板組合而使用時，可使能夠檢測觸 控壓力及觸控位置雙方之區域、與上述觸控位置檢測用觸 控面板之觸控位置檢測區域高度地一致（即，可有效利用 上述觸控位置檢測用觸控面板之觸控位置檢測區域），因 . 此本發明之透明壓電片可與觸控位置檢測用之觸控面板組 • 合起來適當使用。藉此，可提供一種（〗）透明性較高、（2) 可採用各種位置檢測方式，且（3)於其製造時，可直接利用 ❿ 現有之觸控位置檢測用之觸控面板的製造裝置、或者可直 接利用現有之觸控位置檢測用之觸控面板自身的觸控面 板。 第2發明之透明壓電片如第1發明之透明壓電片，其中 上述片狀透明壓電體層之厚度為1〜200 μιη。 本發明之透明壓電片藉由上述片狀透明壓電體層之厚度 為1〜200 μιη，可賦予以高感度及高精度檢測觸控壓力之功 能’而不會破壞觸控位置檢測用觸控面板之觸控位置之檢 φ 測的感度及精度。該厚度自透明性之觀點考慮，較好的是 50 μιη以下，該厚度自觸控壓力之檢測感度之觀點考慮， 較好的是 20 μιη~100 μιη。 第3發明之透明壓電片如第1發明或第2發明之透明壓電 片，其中 上述片狀透明壓電體層含有有機聚合物。 本發明之透明壓電片藉由上述片狀透明壓電體層含有有 機聚合物，可準備並製造大面積之片狀透明壓電體層，故 而可降低製造成本。 143712.doc 201017496 第4發明之透明Μ電片如第3發明之透明㈣片， 上述有機聚合物係偏二氟乙烯，氟乙稀共聚物。 :發明之透明壓電片藉由上述片狀透明壓電體層包含偏 二氟乙烯-四氟乙稀共聚物’而具有特別高的透明性。 第5發明之透明壓電片如第1發明至第4發明中任—發明 之透明壓電片，其中 货方 上述第1透明平板電極進一步包含第i導線部，且 上述第2透明平板電極進一步包含第2導線部。 第1導線部及第2導線部分別係用以將上述第1透明平板 電極及上述第2透明平板電極連接於外部配線之部分。本 發明之透明壓電片藉由上述第丨透明平板電極進一步包含 第1導線部，且上述第2透明平板電極進一步包含第2導線 部’可容易地連接於外部配線。 第6發明之透明壓電片如第丨發明至第5發明中任一發明 之透明壓電片，其中 進一步包含黏著部。 本發明之透明壓電片包含黏者部，藉此可黏附於觸控位 置檢測用觸控面板等任意物體上使用，從而可對其表面賦 予檢測觸控壓力之功能。 第7發明之透明壓電片如第1發明至第6發明中任一發明 之透明壓電片， 其係與觸控位置檢測用觸控面板組合而使用。 本發明之透明壓電片藉由與觸控位置檢測用觸控面板組 合而使用，可對觸控位置檢測用觸控面板賦予檢測觸控壓 143712.doc 201017496 力之功能。 第8發明之透明壓電片如第7發明之透明壓電片，其中 上述觸控位置檢測用觸控面板係電阻膜式或靜電電容 式。 ， 本發明之透明壓電片可不破壞製造成本較低之電阻媒式 -

Description of the Invention: [Technical Field of the Invention] The present invention relates to a touch panel and a transparent piezoelectric sheet. [Prior Art] In recent years, a display device and an input device provided with a touch panel as an input device in front of a display device such as a liquid crystal display have been put into practical use, and are being used for mobile devices such as mobile phones and operation panels of home electric appliances, and the like. . _ Using a display device with a touch panel and an input device allows the user to intuitively operate the device by pressing the display on the screen. In the touch panel that has been put into practical use so far, only the position of the user's pressing (sometimes referred to as a touch position in this specification) can be detected, and the strength pressed by the user (ie, the height (intensity) of the pressing) cannot be detected. In this manual, it is sometimes called touch pressure). On the other hand, in the display device and the input device using the touch panel, the touch panel is disposed in front of the display device. Therefore, in order to improve the visibility of the display device, the transparency of the touch panel p is required. high. As an input device capable of detecting the strength of a press and having transparency, or similar thereto, for example, a touch panel portion including a piezoelectric body serving as a member of an electronic paper, and being provided at the above pressure is disclosed in Patent Document 丨. a first electrode on one side of the electric body and a second electrode provided on the other side of the piezoelectric body. Further, in Patent Document 2, a touch screen system includes: a first sensing system that is coupled with a touch screen to determine a set of position coordinates with respect to each contact of the touch screen; and 2 sensing system 143712.doc 201017496 system, which is combined with the above touch screen, uses the object of the first type to confirm the contact of the touch screen, and uses the object of the second type to invalidate the contact of the touch screen. There is no ability to determine the group of position coordinates described above; and as the first sensing system, specifically, a force sensor disposed outside the visual area of an LCD (Liquid Crystal Display) is disclosed. Further, Patent Document 3 discloses a transparent piezoelectric inductor which is characterized in that a transparent transparent pressure sensitive layer is formed between a pair of opposite transparent substrates, and a transparent pressure is formed therethrough. One of the layers is disposed opposite to the transparent conductive film layer. [PRIOR ART DOCUMENT] [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei.

[Brief Description of the Invention] [Problems to be Solved by the Invention] Although the touch panel portion disclosed in Patent Document 1 can obtain a voltage pulse corresponding to pressing, the touch panel portion does not have transparency as an essential requirement. It can be considered that the transparent shirt is sufficient. Moreover, the material disclosed in the literature [the touch panel disclosed is a resistive film type, but in (4) the electrostatic capacitance type which is easy to detect by multiple points, (b) the ultrasonic type which is suitable for handwriting input and high durability, and ( c) In the touch panel of the position detection method with high light transmittance and high durability, the touch panel must also be developed to detect the touch position 143712.doc 201017496 control position and touch Pressure-controlled touch panel. Further, the touch panel disclosed in Patent Document 1 has a problem that it is difficult to directly switch to a conventional touch panel manufacturing apparatus that detects only the position pressed by the user. If the touch panel can be used to detect the touch position and the touch pressure, the touch panel can be directly used to manufacture the touch panel, or the existing touch position detection can be directly used. The touch panel itself' will be simple and even reduce manufacturing costs. Φ The touch screen disclosed in Patent Document 2 can discriminate the false contact, so it can be said that it proposes the concept of detecting the strength of the pressing, but actually the specific disclosure is as described above 'by the outside of the visual area of the LCD The detector detects the warpage of the substrate, the accuracy thereof is not sufficient, and it is difficult to perform, for example, linear detection. The transparent pressure sensor disclosed in Patent Document 3 also discloses the presence or absence of detectable pressing 'but does not disclose the ability to detect the strength of the pressing. In view of the above, it is an object of the present invention to provide a touch panel or the like which is capable of detecting a touch position and capable of detecting a touch pressure (a height (strength) of pressing) with high precision.
